Detailed Manufacturing Process of 1 4 inch Laminated Glass

The production of 1 4 inch laminated glass involves a meticulous multi-stage process designed to bond two or more sheets of glass with one or more polymeric interlayers, typically PVB or EVA, under heat and pressure. This creates a composite material that maintains integrity upon impact, significantly enhancing safety.

Product Materials:

• Glass Lites: Typically two sheets of annealed or heat-treated (tempered or heat-strengthened) float glass, each approximately 1/8 inch (3.175 mm) thick, combining to form the 1/4 inch nominal thickness. The choice of glass depends on required performance characteristics.
• Interlayer:
  • PVB (Polyvinyl Butyral): The most common interlayer, offering excellent adhesion, impact resistance, and sound dampening. Standard thickness for 1/4 inch constructions is often 0.030″ (0.76 mm) or 0.060″ (1.52 mm).
  • EVA (Ethylene-vinyl acetate): Used for specific applications, particularly where transparency, UV stability, and adhesion to various materials are crucial.
  • SGP (SentryGlas Plus): A rigid interlayer for structural glazing, offering higher stiffness, strength, and post-breakage retention compared to PVB, often seen in 10mm toughened laminated glass and demanding structural applications.
